OK, so the speeds 100% eliminate anything inside the rim moving. Given the age, the odds of it being a notched cross moving have gone way up. Unfortunately the tying will make any diagnosis more difficult. It's hard to know anything without having the wheel in my hands, but I'd try "massaging" the spokes to see if I can cause movement at the cross to produce the "click". If I can't duplicate it, I'd consider raising the overall tension 10%, focusing ion bring any individual low tension spokes (by pitch) closer to the average then test ride.
